Improvement in shingle-machines



CHARLES SHELMIDINE, OF SUMMIT, NEW YORK.

IMPROVEMENT IN SHINGLEMACHINES.

Specilication forming part of Letters Patent No. 116,637, dated July 4,1871.

To all whom 'it may concern:

Be it known that l, CHARLES S1-1ELMID1NE,oi' Sulnniit, in. the county ofSchoharie and State of New York, have invented a new and usefulIniproveinent in Shingle-lildger; and I do hereby declare that thefollowin is a full, clear, a-nd act description thereof, which willenable others skilled in the art to ina-ke and use the same, referencebeing had to the accoinpanying drawing forining part of thisspecification.

" This invention relates to a new and usel'ul iinprovelnent in anattachment to sliingle-machines are two jaws, which are made to slideback and forth on the bar A. The manner in which they are connected withthe bar is seen in Fig. 3. The slides C C, to which the jaws aredirectly attached, are so operated upon by sjn'ings that the jaws areadjusted so as to suit the width of the shingle. The edging-levers niaybe on the outside of the shingle-machine, connected together by coiledsprings, The shingle passes between the jaws B B and strikes against theinside of the gauge-knives I) I), which knives are fastened to thecurved pieces E E. F F are circular cutters, which revolve on pivot-pinsin the jaws. As the shingle passes back the circular cutters begin tocut when the shingle reaches the incline planes G G, which are on thebottoni of the curved pieces E E. As the shingle slides under theseincline planes it lifts the gauge-knives D l) from the shingle, whilethe circular knives out the edges ofthe shingle and make theln straightand parallel with each other. The shingle passes through a groove ineach of the jaws when itis operated upon by the .knives and cutters. Thesaid grooves terminate in the circular openings I-I H, as seen in Fig.l. By these grooves the shingle is coniined on both its sides, and keptin the proper position for the edging process to be performed.

The circular cutters cut by the side of ilanges on the lower portion ofthe jaws, so that the bottoni side ot' the shingle passes through thejaws a little above the bottoni of the circular cutters.

This apparatus is more especially designed for a shin gle-niachine forwhich Letters Patent have already been granted ine, and its applicationwill be readily understood by referring to said machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a shin gle-machine, the jaws B B, construct-edand arranged to operate as herein shown and described.

2. The combina-tion of the gaugingknives D l) and circular cutters F Fin the jaws B B, arranged to operate substantially as and for thepurposes described.

3. The incline planes G G and curved pieces or levers E E, incombination with. the jaws B B, substantially as described.
